My girls are five years apart and I love that age gap. I find that there's much less jealousy between the two of them. My eldest daughter had me for quite a long time and her dad, so there's not that jealousy issue, possessive issue. But they play beautifully together. I wasn't sure they would, but they do. My daughter sort of teaches her through play. They'll have music class; she'll be the teacher for music class, for Barbie class. The imagination takes over. It's truly a joyous experience to watch them. To me, it's just a fabulous age gap.
